I think Alice and Meiling actually relate to each other in some ways:
Both are stage 3 bosses.
Has something to do with the seven colors of the rainbow.
Portrayed as easily forgotten.
Has their own personal army (Dolls and fairy maids respectively).
Both has to deal with Marisa's intrusions.
In their respectivve first apperance, there's a stage5 maid.
Mostly buttmonkeys in fanon,(though very rarely recently).
Kind human-like Youkais.
But I digress.
When it comes to exercising, leave things to me!Yeah, I've been called that sometimes.Ah, by the way, Alice-san.Yet another something is here.Hm, what?The number one martial artist of the Scarlet Devil Mansion, Hong Meiling!
Makes her gallant appearance!You are the Prismatic Puppeteer, right?There are lots of rainbow related stuff among my spell cards, too! Stuff like "Rainbow Taichi". In other words, you and I are allies! We are two and we are one! We are a Kamen Rider with Prism Bicker!Um...... You've lost me completely.
